We have a vast array of high quality cattle available for all your embryo recipient needs. All cattle have been carefully selected to be a part of this top quality herd.


When selecting a recipient female to transfer any of your high quality embryos into it is important to take in a few considerations. Cows that are reproductively sound, exhibit calving ease and have good milking and mothering ability are premium recipient prospects. They must be on a proper plane of nutrition (body condition score 6 for beef cows and dairy body condition score 3 to 4). These cows also must be on a sound herd health program. 


To maximize embryo survival in the recipient female following transfer, conditions in the recipient reproductive tract should closely resemble those in the donor. This requires synchronization of the estrous cycles between the donor and the recipients, optimally within one day of each other. Synchroniza­tion of the recipients can be done in a similar manner and at the same working time as the donor cows. There are a number of different estrous synchroniza­tion protocols with advantages and disadvantages for each protocol. The critical point regarding recipient cow estrous synchronization is the timing must match the time of insemination of the donor cow so that the donor and the recipients have a similar uterine environment seven days later when the transfer takes place. Synchronizing products are more effective on recipient females that are already cycling. “Anestrus” or noncycling cows that are too thin or too short in days postpartum will not make useful recipients.

  • How many days postpartum do I have to wait to flush my donor?
    Donor should be a minimum of 60 days postpartum on flush day. Cows should have received all pre breeding vaccinations a minimum of 30 days prior to collection. All donor animals should be on a rising plane of nutrition in the postpartum period.
  • How often can my donor be flushed?
    Donors can be flushed every 30-35 depending on their post flush heat, however if time is not a factor we will typically schedule donors every 45 days.
  • How many embryos on average do you get from conventional flushing?
    In our facility we are averaging 6.4 grade 1 freezable quality embryos per beef donor. Results can vary depending on individual cows performance ability as some cows may give zero freezable embryos, and our current record is 42 Grade 1 freezable.
  • What is the conception rate of fresh and frozen conventional embryos?
    Typically we tell clients that your embryo conception rate should be roughly 5% lower than your farms AI conception rate. On frozen embryos a typical average is 50-55% and fresh embryos should be 5-10% higher at 60-65% conception rate.
